This halt opened in July 1928 and is situated behind the picture in the side panel, accessed from a steep road off from the A487 road at the start of a footpath leading to Portmeirion. It is at a height of 25 ft (7.6 m) and a distance of just over 1 mile (1.6 km) from Porthmadog. The halt closed on 15 September 1939 and reopened on 23 July 1955. For that short 1955 season of the re-opening of the Festiniog Railway, Boston Lodge Halt was the temporary terminus.
Its main use is chiefly by visitors and staff to the adjacent Boston Lodge Works of the Festiniog Railway Company and by a few walkers. Trains call at this halt only on request and intending passengers are advised to check with train guard before embarking on their journey.
